[QUOTE="Dean2, post: 2235100, member: 26077"] The 303 British was built as a battle rifle and it is an expetionally competent gun for that. Accurate to 800 yards, good knock down power, high rate of fire and tremendously reliable. They are still in wide use here in Canada as a hunting rifle and the Northern rangers only switched from the 303 Lee Enfield to a new rifle last summer.. They were intentionally made with sloppy chambers so they would still feed and fire when dirty and accommodate ammo made in many different places, some like Indian production, was not really close to being in spec all the time. The British never thought about reloading fired brass. It was a one time consumable from their point of view. If you measure new unfired and then fired brass you will see that it stretchs a lot on the first firing. Squeezing that brass back down to its original size means you are working the brass far more than you need to and brass life is going to suffer as a result. We have never done more than neck size 9/10s of the neck with a Lee Collet die or a true neck die. Even after 10 firings I have not needed to "Bump" the neck for them to chamber nicely. If you ever do get to that stage, just turn the neck die down till you can measure .002 of bump. (Lee Collet dies won't bump the neck). Usually happens about the 15th loading. Best of luck and enjoy a great old rifle. [/QUOTE]
